Step 4: Making Slinky Coils and a Slinky Tail
In order to create the slinky body you have to take each half of Slinky and use thin wire to hold them together however far apart works best for you body type. To do this use an exacto knife to cut holes in the middles of the halves and run the wire through one half to the other half and attaching them. I did this in about four places to balance the weight out. The take the tubing and tie it to the top half of the body, take measurements to see where each slinky ring should lay and mark it up with a sharpie. Then cut holes through each ring with the exacto and string wires through all of these consecutively. Do not attach the slinky rings to the bottom except in one single spot. This allows for the wearer to pull the slinky rings up in order to crawl into the costume.
The tail is done in the same fashion except using thicker wire to mold the tail and to get it to bounce back and forth. Also use a paper mache, painted bowl as the base. Just glue it onto the bottom half in the back with hot glue and attach the wires from that point. Keep twisting the wires until the end and use a paper mache oval like ball as the final tip of Slinky's tail! Paint it dark brown and also make sure to paint any wires that were not originally silver so it all looks cohesive.
